Abstract

The present invention provides a resource allocation method and device. The method includes: sending, by a base station, a resource allocation parameter to a terminal, where the resource allocation parameter includes a starting narrowband index and a resource position, where the starting narrowband index is used for indicating a narrowband resource and/or a wideband resource for the terminal to establish a physical shared channel. The embodiments of the present invention solve the problem in existing art that resource allocation for physical downlink shared channel (PDSCH)/physical uplink shared channel (PUSCH) only considers a bandwidth limitation of a 1.4 MHz narrowband so that a user equipment (UE) cannot support machine type communications (MTC) applications with a higher data rate, achieving an effect of being capable of supporting MTC traffic with a higher data rate.

Claims

1. A resource allocation method, comprising:

sending, by a base station to a terminal, a resource allocation parameter via a downlink control information (DCI), wherein the resource allocation parameter comprises a starting narrowband index or a resource block allocation; and

sending, by the base station to the terminal, data on a physical shared channel according to the resource allocation parameter.

5. The method of claim 1, wherein a maximum channel bandwidth supported by the physical shared channel includes one of 5 MHz or 20 MHz.

14. The method of claim 1, wherein the starting narrowband index or the resource block allocation is independently encoded.

17. The method of claim 1, wherein the starting narrowband index is sent through information of variable length.
